Hi yoz,
I have been reading your conversation with marcus. From my point of view, I guess this is nothing to do with which behavior is correct or wrong.I guess what matter is that there is a feature which is useful to the end user (the customers...), I have been thinking about this....
1. From previous version, octane considers what blender exports.
like if the material was assigned as diffuse, or glossy, or specular. Octane reads the same. It is more convenient to assign it on blender by clicking one button.
So we have a head start and focus on the lighting and composition.
2. From current version (v 3.4) most of the materials is considered only as glossy.
so, even if we assign it as diffuse in blender , it returns as glossy in octane, then we have to change the material to diffuse again which when we click the button, it collapses the sliders and we need to collapse again to find where did it go then collapse again to adjust.this process needs more time before giving it a diffuse material.This happens on very first load or during updates or if we add new object with diffuse materials.
I believe, the previous version has this feature and i don't know why this has been removed from the latest version, which I think makes it a setback from the previous version, if there has been complains about it as discussed in the forum, I guess the proper way is to improve it or resolve it and not to remove it. co'z i think its a good and convenient feature not to be scraped from the software.
Well this is just what i think. ur ideals and enlightenment is gladly welcome.
Thanks!! chow!!
